Features

The PMBS3904 is a popular NPN bipolar junction transistor (BJT) commonly used in electronic circuits. Its key features include:
1. Low Voltage Operation: It has a maximum collector-emitter voltage (Vce) of 40V, making it suitable for low to moderate voltage applications.
2. Current Gain: The transistor offers a high current gain (hFE) range of 100 to 300, which enhances its ability to amplify weak signals.
3. Moderate Power Rating: It has a maximum collector current (Ic) of 800mA and a maximum power dissipation of 500mW, making it ideal for small signal amplification.
4. Fast Switching Speed: The PMBS3904 features a significantly fast switching time, suitable for high-frequency applications.
5. Package Types: It is available in various packages, including TO-92 and SOT-23, providing flexibility in design.
6. Temperature Range: It operates effectively within a wide temperature range, typically from -55°C to +150°C.
These characteristics make the PMBS3904 a versatile choice for use in amplifiers, switches, and other electronic circuit applications.

Package

The PMBS3904 is typically available in a TO-92 package type, which is a cylindrical plastic package commonly used for transistors. Other variations may include SOT-23 or surface-mount options, depending on the manufacturer.

Pinout

The PMBS3904 is a NPN bipolar junction transistor (BJT) commonly used in electronic circuits. It typically comes in a TO-92 package with a pin count of three.
The pin configuration is as follows:
1. Emitter (E) - The terminal through which the current leaves the transistor.
2. Base (B) - The terminal that controls the operation of the transistor; a small current at this pin allows a larger current to flow between the collector and emitter.
3. Collector (C) - The terminal through which the current enters the transistor.
The PMBS3904 is widely used for amplification and switching applications in various electronic devices. Its characteristics make it suitable for low-power and medium-power applications.
